Hi, team,
I want encode 12 cameras using nvmedia_iep. And i notice instance ID only support 0~2 , so how to support 12cameras at same time ?

Hi, @wangxuhui1

Please share the code snippet about the instance ID so I can easily look into it. Thanks.

[VickNV]

That’s hardware instances underneath. You can just use NVMEDIA_ENCODER_INSTANCE_AUTO, “2”. Please refer to NvMediaEncoderInstanceId.

hi @VickNV ,
yes i am using the api of nvmedia_iep

NvMediaIEP* NvMediaIEPCreate	(	const NvMediaDevice * 	device,
NvMediaIEPType 	encodeType,
const void * 	initParams,
NvMediaSurfaceType 	inputFormat,
uint8_t 	maxInputBuffering,
uint8_t 	maxOutputBuffering,
NvMediaEncoderInstanceId 	instanceId 
)	

So does it support 12 cameras? Looks only support three instanceId at the same time. Any way can support 12 cameras?

[VickNV]

Yes, you can follow Can h265 encoder support 12 camera? - #3 by VickNV to use auto one.

NVMEDIA_ENCODER_INSTANCE_AUTO: Specifies that the encoder instance ID can be set dynamically during encode.

@VickNV Oh, I see, thx

Hi @wangxuhui1 :
Did you successfully encode 12 cameras at the same time?
Thank you.
